SPECIFICATION forming part of Letters Patent No. 553,915, dated February4, 1896.

Application iled October 5, 1894. Serial No. 524,988. (No Inode/ld Toall whom, t may concern:

Be it known that I, WILLIAM F. KARCH, of Dayton, county of Montgomery,State of Ohio, have invented anew and useful Improvement inHydrocarbon-Burners; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

My invention relates to useful improvements in hydrocarbon-burners; andit consists in means for vaporizing crude oil, such as petroleum, to theend that a thorough combustion is obtained and the oil transformed inthe burner into a vapor. A common defect met with in crude-oil burnersis a failure to thoroughlyvaporize the oil before it reaches the pointof ignition, which results in a constant dripping of the oil from theburner-tip on the grate-bars and into the ash-pit.

The object, therefore, of this invention is to reduce the oil to avaporor gas which readily ignites when it comes in contact with the hot airunder the boiler, without any attending waste or accumulation of oil onthe gratebars or in the ash-pit.

To this end my improvements have reference to parts that will be fullydescribed in the specification, and set out in the claims.

, Referring to the annexed drawings, formin a part of the specification,Figure l is a side elevation of my improved crude-oil vapor-generatorand burner; Fig. 2, a central longitudinal section of the same with partof the burner broken off g Fig. 3, a transverse section ef the vapor orgas chamber, showing the atomizing or vaporizing fans; Fig. 4:, adetached detailview of one of the fans, showing the angle of the vanes.

In the detailed description to follow, similar letters of referenceindicate corresponding parts in the several views.

a designates an elbow-fitting into which a steam-induction pipeb and asteam-induction cone c are fitted.

CZ is a pipe-fitting having an oil-chamber e, and f designates acoupling connected with said fitting d. This coupling has a coneshapedoil-run e that registers with the oilchamber e and through which the oilis drawn by suction created by the steam passing through the chamber c'of the cone c. The steam-cone c occupies a horizontal and centralposition in the oil-chamber c and prohave each three vanes arranged onequal.

angles, as shown in Fig. 4, and lie directly in the path of the oil andsteam as said elements leave the oil-run e and steam-passage c.

The conical shape of the gas-chamber t' directs the oil in an atomizedor vaporous form to the burner m, which is connected to said chamber t'bya reducing-coupling n. The burner-tip m passes through the boilerfront. (Not shown.)

In order that the fans may not be affected by the steam when the burneris not in use and to provide means for keeping said burner free fromaccumulations that might clog it up, I run an auxiliary steam-pipe bfrom pipe Z1 into the gas-chamber Q, both pipes being controlled byglobe-valves g" and g", it being understood that steam is only permittedto pass through said auxiliary pipe when the oil and steam are out offin pipes g and l). The steam is ordinary boiler-pressure, and the oilplaced in an elevated tank will have sufficient gravity or it may besubjected to pump-pressure. As the steam enters the conical-shapedoil-run e a strong suction is created which draws forth the oil, forcingit through the small end of said conicalshaped chamber against the fans,which are driven thereby at a great speed, and said oil thereby becomesthoroughly atomized or vaporized and is delivered to thegeneratingchamber 1l, where it obtains volume and is forced by the steamthrough the burner under the boiler and is speedily ignited and burns awhite Haine.

The dot-ted lines in Fig, 23 show the relative size of the openingthrough which the steam and oil pass to the atomizers or fans, and fromwhich it will be seen the force of said steam is concentrated on thewidest portion of the fan-vanes, which rapidly revolves both fans.

I am aware .that it is not new to place a fan or distributing-blades ina burner of the class herein named. Therefore I do not desire to claimsuch in a broad sense.

Il aving described my invention, I claim as ncwand desire to secure byLetters Patentl. In a hydrocarbon-burner, the combination with the oiland steam induction pipesg and l), of a pipe-fitting I provided with anoil-chamber c, a steam-induction cone c projecting through saidoilchamber, a coupling f provided with a conical chamber e into whichthe cone c pro j eets, and through which the oil passes, a plug providedwith a conical vapor-chamber L of an increased area, and two sets ofatomizing blades or fans each set being independently mounted in thcmouth of the chamber L' adjacent to the front end of the oil and steamchamber c', whereby means are provided t'or thoroughly atomizing a`maximum quantity of oil, substantially as described.

In a hydrocarbon-burner, the combination with oil and steam inductionpipes y and l), of a pipe-fitting (l provided with an oilchamber c, asteam-induction cone @projecting through said oil-chamber, a coupling j"`nected to the pipe l) and communicating with the chamber 'L' at a pointin advance oi' the atomizing-fans, whereby means are provided forgenerating a maximum quantity of vapor, and for introducing steam intothe burner for the purpose of cleansing, without actuating the fans,substantially as described. ln testimony whereof I have hereunto set myhand this 26th day of September7 18H-l.
